Interactive Mode
Each code line is executed and output is seen on the next line. Interactive mode gives
output line by line. It is mainly used to test the code for errors.
To work in the interactive mode, follow the below steps:
Step 1: Click on the Start à Python 3.7 folder.
Step 2: Click on the IDLE(Python 3.7 64-bit). The Python Shell window opens where you
can see the prompt (>>>). INTRODUCTION TO PYTHON
Step 3: Type the following on the Python Shell and see the output:

Python Shell Window
How does the Interactive Mode Works?
When we type on the screen next to the prompt (>>>), the interpreter converts the written
command into machine code. For the output, the machine code is converted into the human
readable format by the same interpreter.
From the above screen, Python can be used to solve high-level complex mathematical
problems or as well as simple arthematic calculations.
Fun If an expression is written in Python IDLE prompt and Enter key is
Fact! pressed, the interpreter will display the result in the next line once it
processes it.
Script Mode
We learnt in the interactive mode that Python automatically processes the expressions or
inputs provided by the user and displays the result. In the script mode, Python does not
automatically process and display the result. The script mode is used to write longer Python
codes. It also allows you to save the programs for later use.
Perform the following steps to use the script mode:
Step 1: Click on the File à New File option.
